The mandatory vs required is for telemetry for engineering purposes and not range safety. Notice the trace goes red at the second burn. The range is not involved there.
As for the green/red transitions compared to the "X", that might just be graphical inaccuracies.

For the record, according to both Jonathan and Gunter's launch statistics, I believe this will the the 200th flight of a Centaur upper stage (excluding mockups).

nose cones?
No caption help here but I think we can assume this is the S-V dummy being mated 8 weeks before SA-2 flight. Or it might be the internal tank shown inside the S-IV dummy drawings.

View of MUOS-1 in STK on NASA ELV webcams, still no actual shots of the vehicle
